Injecting machine for injecting mixture of two different liquids in first-in and first-out manner

An injecting machine for two different liquid materials, comprising:

• a generally horizontally disposed injection cylinder having a nozzle disposed on a distal end thereof;
• a plunger reciprocally received in the injection cylinder for moving between an advanced position and a retracted position, the plunger injecting a liquid mixture of the two different liquid materials as the plunger moves to the advanced position;
• plunger moving means for causing the plunger to move between the advanced position and the retracted position;
• and
• a mixing mechanism disposed on the injection cylinder for mixing the two different liquid materials together to feed the liquid mixture into the injection cylinder,
• wherein the plunger includes a front portion having a helical groove formed on an outer circumferential surface thereof to allow the liquid mixture fed from the mixing mechanism to pass through the helical groove for collecting in a forward space formed forward of the front portion of the plunger, and
• wherein the mixing mechanism comprises:
• a body mounted on a surface of the injection cylinder;
• a valve member vertically movably received in the body;
• a valve actuator secured to the body for driving the valve member to move between open and closed positions;
• a mixing block disposed to extend generally vertically attached to a lateral side of the body;
• a screw rotatably accommodated in the mixing block;
• a screw rotating mechanism supported on the mixing block for rotating the screw;
• and
• a first passage formed in the mixing block and extending to the body for causing the liquid mixture to flow out of a vicinity of a distal end of the screw and being in communication with the injection cylinder,
• the first passage extending generally horizontally.

An injecting machine for two different liquid materials, the injecting comprising:

• a mixing mechanism for mixing two different liquid materials together to provide a liquid mixture;
• a generally horizontally disposed injection cylinder mounted to the mixing mechanism for receiving the liquid mixture from the mixing mechanism, the injection mechanism having a nozzle disposed on a distal end thereof;
• and
• a plunger reciprocally received in the injection cylinder for moving between an advanced position and a retracted position, the plunger being configured to inject the liquid mixture out of the nozzle of the injection cylinder as the plunger moves to the advanced position, and the plunger including a front portion having a helical groove formed on an outer circumferential surface thereof to allow the received liquid mixture to pass through the helical groove for collecting in a forward space formed forwardly of the front portion of the plunger as the plunger moves to the retracted position;
• wherein the mixing mechanism comprises:
• a body mounted on a surface of the injection cylinder;
• a valve member vertically movably received in the body;
• a valve actuator secured to the body for driving the valve member to move between open and closed positions;
• a mixing block disposed to extend generally vertically attached to a lateral side of the body;
• a screw rotatably accommodated in the mixing block;
• a screw rotating mechanism supported on the mixing block for rotating the screw, screw;
• and
• a first passage formed in the mixing block and extending to the body for causing the liquid mixture to flow out of a vicinity of a distal end of the screw and being in communication with the injection cylinder,
• the first passage extending generally horizontally.
